Christ said, "Resist not evil", and we do not understand it until we discover that it is not only moral but actually the best policy, for anger is loss of energy to the man who displays it. You should not allow your minds to come into those brain-combinations of anger and hatred.
Swami VivekanandaNever allow weakness to overtake your mind. Remember Mahavira, remember the Divine Mother! And you will see that all weakness, all cowardice will vanish at once.
Swami VivekanandaIf you intend to study the mind, you must have systematic training; you must practice to bring the mind under your control, to attain to that consciousness from which you will be able to study the mind and remain unmoved by any of its wild gyrations. Otherwise the facts observed will not be reliable; they will not apply to all people and therefore will not be truly facts or data at all.
Swami Vivekananda
